Symbol Cause
The residual current that flows from the plus
or minus input via the PV generators to earth
exceeds the permitted value.
Due to normative specifications, the inverter
automatically switches off while the fault is
present.
An internal component in the inverter is
defective.
The inverter is not feeding into the power
grid or is only feeding in with reduced power.
Despite the reduction in output, the max-
imum permissible temperature has been
exceeded.
The inverter does not feed into the power
grid until the permissible temperature range
has been reached.
The inverter cannot detect an internal com-
ponent or it does not match the other com-
ponents.
The inverter is not feeding into the power
grid.
The connection for the internal components
has been interrupted.
The inverter does not feed into the power
grid.
–
–
–
The insulation resistance between the plus
and minus input and earth exceeds the
permissible value.
For safety reasons, the inverter must not
feed into the power grid.
The inverter has incorrect unit data or unit
data is missing.
It therefore cannot feed into the power grid.
There is no data connection between the
inverter and the energy meter, or the data
connection between these is incorrect.
Outer and neutral conductors are inverted.
For safety reasons, the inverter must not
feed into the power grid.
The inverter cannot feed into the power
grid because it does not have any valid
parameters.
The inverter reduces its output power be-
cause the maximum permissible temperature
has been reached.
The inverter could not correctly read the set
country from the cylinder.
The inverter's internal fan is defective.
The inverter may feed into the power grid
with reduced power.
